Stoke were hoping to return to the Premier League this season, but have endured a difficult time in the Championship, and now face having to move players on.
Jack Butland is one player expected to go, and it may be difficult to keep midfielder Allen too, with the Welshman having admirers up in the Premier League.
The Telegraph now claim that Watford and West Ham United are expected to fight for Allen's signature, potentially offering him a return to the top flight.
Allen, 29, has hit six goals and four assists so far this season, and scored 10 times in his first two seasons at the club having joined from Liverpool back in the summer of 2016.
The Welshman may well fancy a return to the top flight, and a move to West Ham would be interesting given their past interest in his services.
David Sullivan was quoted by the Daily Mail in February 2018 as saying that West Ham offered a huge £25million to sign Allen in January of that year, but Stoke refused the deal.
Allen surely wouldn't cost that kind of money now, and would give Manuel Pellegrini a proven Premier League midfielder, though some may feel he's too similar to Mark Noble.
